Randomly felt breathless doing work

[Grace360]

So my anxiety and depression has been paritcularly bad lately. I was just really working on a last minute project, singing along as I made some work on google sheets when I started getting breathless and my body felt weird. Almost as if something malcuntioned in my body,, or something happened. I heard long ago about aortic valves bursting or whstever. My past frantic research can sometimes catch up with me and I worry, so now I'm worried about that among other things. Just trying to calm myself but still worried how I got breathless so suddenly like that. I wasnt even really anxiety-ridden in that moment.
